SELF-DISCHARGING CAR. t

Application filed July 13, 1928, Serial No. 292,521, and GermanyDecember 1, 1927.

The invention relates to self-discharging cars of the type in which amember effect ng the discharge of the car is in connection with theundertrame by a lever and link gear which is actuated by a compressedair gear. The object of the invention is a discharging gear of this typewhich is of a particularly simple construction,

In order to allow of the invention to be more easily understood, anembodiment of same is diagrammatically illustrated by way of example inthe drawing which accompanics and forms part of this specification. Inthis drawing Figure 1 is an end view of the self-dischargin car inloading position, and

Figure 2 is a corresponding view in discharging position.

The box A of the self-discharg1ng car is tippingly mounted on theunder-frame B by means of supports )rovided on the latter and havingtipping earings b and has a discharging door 66 The latter 1s in a knownmanner connected with the underframe B by a system of levers a (4 A linkand lever system a b is interposed between the box A itself and theunderframe B, the lever 15 being rigid on a shaft 6 mounted on theunderframe B. The shaft 6 further carries a lever 6* connected theretoby a,

coupling means (not shown), e. g. a toothed coupling. The latter isdesigned so as to enable the lever b to freely rock a certain angleabout the shaft 5 before the latter takes part in this rocking motion. Acatch 1) is rigid on lever b and adapted to engage a pin a laterallyprojecting from link a oi the sys tem at 6 Figure l. A compressed aircylinder C is swingingly mounted on the underframe, the piston rod 0 ofwhich cylinder is guided by means of a roller 0 in a slotted bracket Dpreferably mounted on the'box A, and is further connected to lever 5" bya link E.

In the loading position the parts described assume the positionillustrated in Figure 1, in which the system a Z2 is in or nearly in onedead position and secured therein by the catch 6 of lever b engaging thepin a of the link a. When the car should be discharged, compressed airis supplied to the cylinder C, The piston rod '0 then first shiftswithin the slotted bracket D and rocks the lever Zr byjmeans of link E,lever b first rocking freely on shaft 6 'When this takes place, thecatch, 6 releases the pin a of link at At-the'end of this motion lever bengages shaft 6 and rocks the system (0* 6 out of dead position, thissystem thereupon tipping the boX A into discharging position. When thecar should be moved back to loading position, the air supply to the gearC c is reversed, whereupon the system a Z2 and therewith box Aisreturned to initial position by piston rod 0 and link E connectedthereto. Toward the end of this motion, in which the box A together withthe system a 6 leads with regard to the system E 6 under the, action ofthe weightof the door a that closes itself also the catch 6 re-engagesthe pin efiand locks the discharging gear.

What we clami, is

1. In a self-discharging car an underframe, a tipping part and acompressed air gear mounted on said underframe, a lever tulcrumed onsaid undertrame, a link connecting said lever to said tipping part,another lever fulcrumed on said undert'rame, another link connectingsaid last-named lever to the piston rod of said gear, a bolt rigid onsaid last-named lever and adapted to lock said first-named link in theloading position of said tipping part, and means for coupling with oneanother said two levers at a determined moment after said gear has cometo act.

2. In a self-discharging car an underframe, a tipping part and acompressed air gear swlngingly mounted on said underframe, a levertulcrumed on said underframe, a link connecting said lever to saidtipping part, another lever fulcrumed on said underframe, another linkconnecting said last-named lever to the piston rod of said gear, a boltrigid on said last-named lever and adapted to lock said first-named linkin the loading position of said tipping part, means for coupling withone another said two levers at a determined moment after said gear hascome to act and a slotted bracket mounted on said tipping part andadapted to guide the piston rod of said gear.

3. In a self-discharging car an underframe, a tipping part and acompressed air gear mounted on said underframe, a lever fulcrunied onsaid nnderfraine, a link on neoting said lever to said tipping part, an-

other lever fulcrumed on said underframe co axially to said first-namedlever, another link connecting said last-named leverto the piston rod ofsaid gear, a bolt rigid on said last-named lever and adapted to'locksaid first-named link in the loading position ofsaid tipping part; andmeans for coupling With one another said two levers at adeterminedimoinent after said gear has come to act. p
